This invention relates to a window sash or means enabling a window to employ one or more glass panels or li 'hts in combination with means which releasably clamps the same in position water-tight against the frame, and which when released, may be readily moved for replacement, cleaning, ventilation or otherwise.

It is also an aid to provide a novel construction in which the glass lights or panels form a double wall providing an air or insulating space between the same.

The more specific objects and advantages of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings Figure 1 is a front elevation of a window constructed in accordance with my invention, the same being broken away and partly insection to disclose details,

Figure 2 is a horizontal sectional view taken substantially on the line 22 of Figure 1, j x

Figure 3 is a vertical sectional view taken on the line 33 of Figure 1,

Figure 4 is a vertical sectional'view taken on the line 44 of Figure 1, and I Figure 5 is a horizontal sectional view taken on the line 55 of Figure 1.

Referring specifically to the drawings, the sash illustrated has a frame at 10 which is square, rectangular, or any other approved shape and of any desired material such as metal as shown, wood or the like. The sides, top and bottom of the frame are of channel form and intermediate therein have mullions 11 fastened thereto, whereby the illustrated construction accommodates four glass panels or lights at 12,-it being understoodof course that the device may be of such size or construction as to accommodate any desired number of the lights and that instead of being embodied in a window sash, the invention may also be practiced in connection with lights of doors, ventilators or at any other location. Disposed against the inner surfaces of the frame 10 and the mullions 11, are gaskets 13 and 14 respectively, which may the said .under the hinged joint of the lower plate 26 be of rubber, leather, felt or any desired material, The glass panels or lights 12 engage gaskets and form a water-tight joint therewith. i 7 At the side, top and bottom ofthe frame 10', pairs of clamping plates 16 are provided, which clamp the lights 12 against the gaskets. Said pairs of clamping plates 16 are hingedly. connected as at 17 whereby they may be contracted and expanded. Such plates 16 have portions :18 whichbear directly against the lights and also have extending inwardly therefrom side flanges 19. l will become apparent from a consideration The flanges 19 ofthe'upright plates 16 have links or levers 20 pivoted thereto at 21 and which links or levers are pivoted to gether and .to brackets 21 by means of bolts or pivot pins2'2. Brackets 21 havesleeves 23 in which a rod 24 is disposedsuch rods having abutments 25 thereon engaging the to lowermost sleeves 23. One of the rods 24 of each pair carries a lug or abutment 26 which 3 is disposed under the hinged joint of the Q lowermost pairs of plates 16 so that as the rods 24 are moved upwardly, the joints will be broken to aid in contracting said plates 16;

An operating lever is provided at 27 being fulcrumed at 28 to a bracket 29 located within the frame. A draw cord or the like 30 is connected to the lever 27 to actuate it. Said lever 27 at its inner end has an arm 30 through which the central rods. 24 pass and above which said rods have nuts 31 thereon.. Cranks 32 extend from the pivot means or shaft 28 and suspend the outer rods 24, the latter pass- .85 ing therethrough and having nuts 33 above the same.

As a result of the construction described, a downward pull on the cord 30 moves the inner end of lever 27 upwardly and the cranks 32 upwardly, through the rocking of the shaft 28. Since the lever :27 and cranks 32 are disposed under the hinged joint of the upper plate 16 and the lug 26 is disposed 9 5 and thelevers 20 are connected to the other plate 16, such plates will be contracted and moved away from the glass, panels or lights 12, thus freeing them whereby they maybe removed, replaced, adjusted, or the like:- i

Upon release of the core 30, the Weight of the parts Will be sufficient to restore them to normal position and into clamping engagement With the glass panels or lights 12, se-v curing such lights in their closed positions or in adjusted positions as preferred. By using the oppositely disposed lights 12 an air space is provided which is desirable as an insulator of heat and cold. If desired, the light at one side of the Window may be omitted, in p Which event theportions 18 would directlyengage the gasket or Window frame portion.

adjacent the same.

Various changes may be resorted to provided they fall Within the spirit andscope of the invention.
